And here is yet another option:-

• Export just the foot into Lightwave ensuring that the model is in its zero position. (IK chains off. Window/Joint Parameters/Zero Figure. Hip AND BODY x, y ,zTrans = 0.000)
• Extrude from where the toes would be to form the rounded toe cap.
• Save just this new toe cap in OBJ format.

Now for the fun, look at how the Low Polygon Poser 2 figures change their hands. Its not by adjusting each finger but rather by selecting the hand and turning the "handType" dial. You effectively swop in other geometry. Copy this principle for your toes.

The advantages are that all your existing body morphs will still work and you will not have a visible seam at the toe/foot junction. I grant you this is not for beginners but it may help to know the options available which you may want to look at later. I understand JeffH knows the whereabouts of a tutorial on this (entitled Head Switching???)

Hope this helps.
